Redsail technology cutters have been around sometime and from various sites and experience are a well made Chinese model. The vinyl cutter models vary in look from one manufacturer to another however they mostly incorporate Redsail technology which is the part that I wanted to highlight here.

Redsail vinyl cutters have website which has the generic driver available if needed but also what I have noticed is that it has a troubleshooter.

Here are the links:
